Problem with second storage

We got two Eva 5000 storage systems ( called Eva1 and Eva2 ) which are managed by same appliance.

When I made a host description on Eva2 storage everything works good. However, when I made the same things on my Eva1 storage, my server couldn't communicate with storage and 'spmgr display' gives "Error: Could not transfer data with agent." error.

I have to give some space to my server from Eva1 but I couldn't. Is there any configuration I forgot to do?
